[@donaldshields2483]

Another good job but you always do a good job God bless

[@jaybats7865]

Awesome job. You’re knowledge is incredible. Thanks for the fun

[@TheRangerDale]

Very Good Buddy, Think head nail on the head saying working on Collins radio's can be a night mare, From the owner to getting in and doing the job.Trying to keep things clean and neat and no damage to outside area..Thanks for the info and efforts made for us to understand well clear.. 73's Buddy

[@TRXLab]

Excellent repair Buddy! Thumps up. Thanks for sharing 73

[@TheRadioShop]

Thanks Peter. I like these Collins. Fun to work on.

[@ncque]

All of the screws are "clocked." They are faced in the same direction. All the outlets and switches in my new house have screws pointing north and south. It is a nice little touch added by the electrician.

[@danielsteele7544]

You make it look easy,thankyou for teaching us,love your videos.

[@PelDaddy]

Thanks for another nice vid. Sometimes things aren't so tough to troubleshoot, even if it takes a lot of effort to implement the fix.

[@TheRadioShop]

Thank you for stopping in. you are right about that. This was the case here. Finding the problem was easy. Getting to it, another story....

[@mikesradiorepair]

Currently uploading my one easy one for the year. Another classic brought back to life.

[@TheRadioShop]

Great, I want to have a look :-)

[@mikesradiorepair]

+The Radio Shop I forgot to ask. How do my radios keep ending up on your bench. ;)

[@TheRadioShop]

He he. They just do. How I have it planned out. I have a direct worm hole to you location...

[@mikesradiorepair]

+The Radio Shop Now I just need to figure out how to get them to wormhole their way to me.

[@TheRadioShop]

Well, I had to use Borg technology and nano probes.....

[@MrHarveyluke]

Good video showing the service from troubleshooting, finding, and fixing the problem. You right about using the cheaper analog meter for checking continuity. I usually will use the beep setting on my DVM so I won't have to look away at the meter face.

[@TheRadioShop]

Thanks, Yes it is nice to hear the tones from the meter. In this case it was so easy to troubleshoot. Was barely any thinking in this one.

[@radiotvgod]

@@TheRadioShop how do I contact you?

[@bundylovess]

Good job mate lot of components jammed in under there lol and once again another quality repair

[@TheRadioShop]

Thanks allan. Yes it is packed full of stuff. Not much free room to repair in.

[@MrCarlsonsLab]

Two thumbs up Buddy!

[@TheRadioShop]

Thanks a lot Paul and thanks for stopping by,

[@saturn5tony]

Awesome repair buddy, wow, never new that about the screws, thx4sharing

[@TheRadioShop]

Yep those Collins guys are particular about originality. Most folks never knew about the screws. Thanks for stopping in Tony.

[@mikefinn2101]

Great job nice video thanks mike

[@Beretta96Dan]

Interesting repair, Buddy. Thanks!

[@TheRadioShop]

Thanks Dan. Fun rigs to work on.

[@PapasDino]

Boy, I thought I was OCD about uniformity...Collins collectors have me beat! Good job Buddy! 73 - Dino KL0S

[@TheRadioShop]

Yep, those guys are very curious about their gear being stock and original.Thanks Dino.

[@PaulHigginbothamSr]

Talking about the same scew head position. On Boeing aircraft every screw has a torque spec. The position is not important but any tool mark whatsoever is important. The plane will not pass inspection.

[@larryk4mu240]

Hi Buddy, good repair video. Repair may have been simple to troubleshoot, but no less important, radio would not work without the repair and the knowledge to repair. As for the analog meter, like my uncle use to say, “just because it is cheap does not mean it will not work”, (he worked on and restored model A’s & T’s Fords. He would heat his soldering iron in a wood stove so he could solder the coil when rebuilding a starter solenoid, while I was crushing corn cobs in his vise. Liked the video. 73

[@TheRadioShop]

Thanks you Larry. And thanks for sharing that story. One day I may modernize the shop. But the old and cheap gear do quite well.

[@larryk4mu240]

You said it my friend. It does not have to have a digital readout to get the job done. 73

[@CharlieTechie]

Good job and interesting video, thanks for sharing.

[@TheRadioShop]

Thanks for watching Chuck.

[@ne2i]

These Collins rigs are pretty reliable. Most of the time I look at relays and switches first for oxidation. Radios like to be used and left sitting these kind of problems occur.

[@TheRadioShop]

Good point.

[@judges69]

Wow, great repair.

[@TheRadioShop]

Thank you, love these old radios.

[@laceradewilde4056]

Sure wish other manufactures used relays that easy to clean. LOL Beautiful rig. Enjoyed the work thru as always. Thanks for the ride!

[@wiltonarmstrong2781]

That is a really nice looking radio would be nice to have one lol

[@lesjohnson9740]

Good stuff yet again good watching, Les G4XMX.

[@TheRadioShop]

Thank you for watching Les.

[@Etherionix]

Check out "crocus cloth" for cleaning those relay contacts. Just a thought.

[@TheRadioShop]

Thanks Don

[@dennisqwertyuiop]

good job I should get the easy ones because you can fix the hard ones

[@TheRadioShop]

Seems I get all the hard ones. Although the problems were simple the repair took some time.

[@MrBugsier5]

old fasion quality, nice!

[@TheRadioShop]

Thanks

[@is0ivg270670]

I am looking for it with accessories .. Do you have for sell ?? thanks .

[@slaznum1]

Great stuff as always, I always wondered about modern line voltages in vintage radios but it seems to me the components can handle a slightly higher voltage what do you think?

[@TheRadioShop]

Thanks, well some tubes are meant to be operated at a certain voltage. Higher line voltage can cause tubes to over heat. Say like screen voltage that should be around 100 volts may tip 150 volts. May not last as long. This is why most that run vintage stuff uses a variac to turn the voltage down. I have a receiver that does not like 120 volts. Runs very hot and becomes distorted. I use a variac at 110 and it is fine. Other stuff no problem.

[@g1fsh]

Another very nice radio Buddy. When u say its been repainted are there places that will repaint a radio and put the lettering back on the front as it should be in the US?

[@TheRadioShop]

Thanks Gary. I know of no places that do that anymore. There used to be. Most folks are now DIY style and have great results. You can buy or make the letters you need with todays technology. After close inspection I fond that the from panel was original. Only sides top and bottom were repainted on this rig.

[@timothywstlwn]

were do you get these radios I just want too do dxing new radios are boo kooo bucks I would like a vintage radio but restoreing it is booo kooo bucks also I liked radio shack but they is gone

[@douro20]

How long have you been working on Collins equipment?

[@TheRadioShop]

The first piece I ever worked on was somewhere about early 80's. Been a long time ago,
